SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 421,650, dated February 18, 1890. Application filed August 23, 1889. Seria1N0. 321,796. (No model.)

To all whom it may concern:

the estate of ALFRED O. NEAIIL, deceased,)

both residing in the city and county of Phila-" delphia, State of Pennsylvania, said ALFRED O. NEALL having also resided in the city and county of Philadelphia, State of Pennsylvania, do hereby state that the said WILLIAM H. BAGLEY and ALFRED O. NEALL have invented a new and useful Improvement in Spring-Motors, which improvement is fully set forth in the following specification and accompanying drawings.

This invention relates to a mechanical motor employing springs as the prime motive power; and it consists in the employment of specially-constructed windin g and unwinding drums or cylinders, an automatic compound pawl-and-ratchet mechanism, and a novel form of brake, together with the general arrangement of the parts, as will be hereinafter more fully set forth.

Figure 1 represents a perspective view of the motor entire. Fig.2 represents an end elevation thereof. Fig. 3 represents a top plan View thereof. Fig. 4 represents a transverse vertical section of a portion thereof. Fig. 5 represents a detail view of-the compound pawl mechanism, Fig. 6 represents a detail perspective view of one of the springs in position. Fig. 7 represents a sectional view of a portion of the compound pawl mechanism. Fig. 8 represents a side view of the bell mechanism.

Referring to the drawings, A designates the supporting-frame, of suitable form and material, provided With a lower central tie-rod 2, two tie-rods 3 3, a power-shaft 4, having a square body, drum-shafts 5 and 6, and an upper power-transmitting shaft 7,wliich parts, in addition to their several functions, are combined to strengthen and give rigidity to the said frame. On the power-shaft 4 are mounted a series of springs 8, whose inner ends are constructed with slots 9, to engage studs 10 on arborsll, which are formed with square openings to fit over the square body 10f shaft 4, and the outer ends of said springs are attached to one of the side tie-rods 3. A series of divisional guards 12, each comprising three integral arms, two of which are secured to the side tie-rods 3, and'the other dependin g vertically for attachment to the lower tie-rod 2. These guards are formed with a central collar 14, through which passes the power-shaft 4 and the arbor 11, and are arranged on the outside of the two outer springs 8, and between all of the said springs to confine their coils in proper position. Be tween the central collars 14 of guards 12 and the arbors 11 of the springs a series of washers 15 are located and keep the parts in their adjusted position and prevent the springs from hearing on the collars 14 of the guards. The depending arms of said guards are held separated by collars 16,which are held stationary by a jam-nut on each side. A shield-plate 17 is connected at its two sides to the tie-rods 3, and covers the upper parts of the springs 8, and prevents contact therewith of parts above said springs.

'On the end of shaft 4 is keyed a mastergear 18,.which meshes with a pinion 19 on the end ofishaft 5,-the latter shaft having thereon a convex conically-tapered drum 20. The shaft 6 has a concave conically-tapered drum 21 thereon, withits reduced end reversely arranged to that of the drum 20. One end of the drum 21 has a pinion 22 in conneotion therewith, meshing with a pinion 23,

attached to the winding mechanism. Said drum 21 is also provided with a pawl and ratchet 24, to prevent a'backward movement thereof. A cord or cable 25 is attached at its ends to the enlarged parts of said drums, and

.25, to prevent straining of said cord or cable.

A gear 27 is securedon the projecting end of shaft 6, and meshes with a pinion 28 on the end of a short shaft 29, and upon the opposite end of the latter shaft is secured a gear 30, meshing with a pinion 31 on the power transmitting shaft 7. Shaft 7 has a brakedisk 32 thereon, and a pulley 33, from which power is taken.

An arm 34 is attached at the upper part of one side of the frame, and has a spring thereunder and impinging thereagainst to hold the same in a normally-elevated position. The said arm is secured to the end of a short horizontal shaft or pintle 35, to the opposite end of which is connected a curved brake-arm 36, carrying a shoe 37, of rubber or analogous material, adapted to bear against the brake-disk 32. The upper end of a pull-rod 33 is attached to the free end of the arm 3i, and eX- tending down through a suitable guide on the frame is connected to the rear end of atreadle 39, and by depressing said treadle the brake is withdrawn from contact with the disk 32 against the counteracting resilient effort of the spring under arm 34-, which normally keeps the said brake in contact with the disk.

The pinion 23 is keyed to one end of a shaft 40, having bearing in the side of the frame, and in a plate 41, supported at a distance from said frame. A ratchet -wheel 42 is mounted on shaft t0 at a point outside of the frame, and between the same and the outer plate 4-1. The upper part of the plate 41 is provided with a slotted extension 43, in which is mounted a pin 41-, having a link-arm 45 attached to the outer end thereof, and to the latter is secured the short member of an elbow-lever 46, fulcrumed on a rod 47, secured to the frame and provided with an elongated arm or lever projecting upward within convenient and accessible distance of an operator. Two arms &3 a9 are pivotally attached to the inner end of pin at, and to said arms are movably secured two arms 51, having apertures at their lower ends adapted to pass over shaft 40, and are formed also with elongated slots 52 in the body thereof for the purpose of receiving retention and actuating pins 53, 54, and 55 on the inner side of a pressure-block 56. The central pin 5a is a headed stud adapted to hold the pressureblocks 56 in connection with the arms 50 51, which, in connection with the lower pins 55, retain the said pressure-blocks in a normallyadjusted position, andthe upper pins 53 are adapted to bear against spring-actuated pawls 57 and lift them from engagement with the ratchet-wheel L2. The said pawls are arranged in the same direction and are thereby capacitated for pusl1-a11d-pull pawls.

Pins 53 project from the outer faces of the pressure-blocks 56 and have movement in curved slots 59 in a slide-plate 60, mounted against the outer plate 41. The plate 60 is constructed with a central elliptical opening 61, through which projects a bearingshoulder (S2 of the plate ti and limits the vertical movement of said plate 60. A lug 63 is formed with the lower end of plate 60, and has a rod (3i secured thereto, which passes through a guide 65, attached to the lower end of plate 41,.and is encircled bya coiled spring 66,11aving bearing at its upper and lower ends against the lug 63 and guide 65. This spring tends to keep the plate (30 normally elevated and thereby throw the pawls 57 out of engagemcnt with the ratchet-wheel 42. The lower end of the rod (it is formed with an eye, to which is attached the upper end of a pull rod or cord (57, connected at its lower end to a foot-treadle 68. A headed pin 69 passes through a slot 70 in plate il into the plate 60, and avoids a lateral displacement of the latter plate in either direction.

The arms 50 51 are depressed by pushing the lever 46 backward, and thereby the pawls 57 are brought into proper position with relation to the ratchet-wheel'42. The treadle 68 is pressed downward and the plate 60 lowered, together with the blocks 56, thus allowing the springs of pawls 57 to force said pawls into engagement with the ratchet-wheel 42. By a reciprocation of the lever l6 the ratchetwheel is given a substantially-continuous rotation, which is imparted to the motor-springs through the intermeshing-gear, and at the same time the cord is unwound from the drum 20 and wound upon the drum 21. To start the mechanism in motion, the treadle 39 is depressed to release the brake-arm 36 from contact with the brake-disk 32, and the motorsprings and connecting-gearing released to impart motion to shaft 7 and to pulley 33. During this operation the cord will wind back on drum 20 from drum 2]..
